in which the value of a data item (such as time) is represented by a continuously variable physical quantity that can be measured (such as the shadow of a sundial)
Origin: Early 19th century; from analogue, from ἀνάλογος, from ἀνά + λόγος.
In chemistry, a structural analog, also known as chemical analog or simply analog, is a compound having a structure similar to that of another one, but differing from it in respect of a certain component. It can differ in one or more atoms, functional groups, or substructures, which are replaced with other atoms, groups, or substructures. A structural analog can be imagined to be formed, at least theoretically, from the other compound. Despite a high chemical similarity, structural analogs are not necessarily functional analogs and can have very different physical, chemical, biochemical, or pharmacological properties. In drug discovery either a large series of structural analogs of an initial lead compound are created and tested as part of a structure-activity relationship study or a database is screened for structural analogs of a lead compound. Chemical analogues of illegal drugs are developed and sold in order to circumvent laws. Such substances are often called designer drugs. Because of this, the United States passed the Federal Analog Act in 1986.
